Installation of the gem fails

[assimovt]

Redis backend for Git - sounds interesting :) Tried to bundle install, but looks like its not in Rubygems, also tried to install against this Git repository with no success. Hints?

It's not in rubygems yet, because the support for it isn't in mainline rugged yet (there is a bit of a dependency chain, see pull requests for rugged and for libgit2 backends).

Can you post a copy of bundle install errors? I may be able to help. One reason for failure I know about is the inter-gem binary dependency (rugged-redis needs to link to rugged and also include rugged's header file), which prevents parallel bundle install with --jobs=[x].

Yep, I have noticed its not in Rubygems and also checked the mentioned pull requests. I am trying against your repos though. Here is my Gemfile and the output of bundle install. Cheers!

Ah, I think you may be missing the git submodules. Try this in your Gemfile:

gem 'rugged', git: 'https://github.com/redbadger/rugged', branch: 'backends', submodules: true
gem 'rugged-redis', git: 'https://github.com/redbadger/rugged-redis', tag: 'v0.1.1', submodules: true

Thanks for spotting this, I need to update the readme to say the correct thing. Let me know if this worked.
